I have a corner shower that was installed about 20 years ago (so no clue who the manufacturer was) and two of the bottom four plastic brackets have broken and I can't find them anywhere! I have talked to various fabricators and I'm being told metal replacements or copies created on a 3D printer would be between $400 and $500 PER PIECE!
It's a basement shower and not used very often, but am struggling to believe I can't find some of these or a suitable replacement for a much more reasonable cost!
Can anyone help?

Thank you!

If you have the piece, have you tried gluing together with a super glue. Did mine 2 years ago and still good.
